Page "Pandu" Paragraph 1

After Vichitravirya's death his mother Satyavati sent for her first born, Rishi Veda Vyasa.

According to his mother's wishes, he visited both the wives of Vichitravirya to grant them a son.

Ambalika was instructed by Satyavati to keep her eyes open lest she would bear a blind son like Ambika's ( Dhritarashtra ).

She did keep her eyes open but she became pale after seeing the formidable form of the Sage.

Therefore, Pandu was born pale.
